METALLIC MEASURING VESSEL.

SPECIFICATION forming part of Letters Patent N o. 657,000, dated August28, 1900. Application filed Tune 19, 1900. Serial No. 20,349- (Nomodel.)

To all whom t may concern:

Be it known that I, GEORGE W. MOKIM, residing at Martins Ferry, in thecounty of Belmont and State of Ohio, have invented cere tain new anduseful Improvements in Metallic Measuring Vessels, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying' drawings, in which- Figure l is a perspective viewof my im` provement. Fig. 2 is a vertical section of the same. Fig. 3 isa vertical section, on an enlarged scale, of the lower or chime end,illustrating the manner in which the metal is bent to form the saidchime end. Fig. 4 is a similar view illustrating the manner in which thechime end is treated to produce my improved construction of vessel. Fig.5 is a view illustrating the manner in which the bottom is set inposition. Fig. 6 is a View showing the manner in which the lower end ofthe bottom is swaged to form an internal locking-flan ge for retainingthe bottom in position.

Heretofore in the manufacture of metallic dry measures intended for hardand rough usage-such, for example, of the type shown in my Patent No.212,721, dated February 25, 1879-it has been the custom to form thebottom portion of a single sheet of metal, with one edge folded over inone or more layers to produce a thickened chime portion, the sev-1 eralfolds being so arranged that the upper end of one or more membersthereof form a rest for the bottom of the vessel to seat on. In themanufacture of metallic vessels having a chime portion made up of aseries of folds, as aforesaid, it has been found necessary to provide asecure rest or supporting edge for the bottom plate to use a number offolds to produce a required thickness to make the upper orbottom seat ofthe chime project sufficiently inward, so as not alone to support thesaid bottom, but also to serve as a permanent means for preventing thebottom plate being pushed down through the chime end. Again, when but asingle inturned fold has been used-as shown, for example, in Fig. 2 ofmy patent aforesaid-the bottom-supporting portion thereof of necessitymust be bent out quite a considerable Way from the wall of the vessel.This latter construction produces an inner fold having a flexibility toogreat to permanently stand against rough usage, as the frequenthammering on the bottom by constant dropping of merchandise into thevessel, etc., soon causes the said rest portion to bend down to such anextent as to make the joint of the bottom with the body of the vesselweak and loose and unfitting the vessel for measuring dry articles ofgrain-like form. My present invention particularly lies in the novelconstruction of the chime end of the vessel, and it compreheuds in itscomplete construction a vessel having the folded portions closelycompressed and the upper or rest portion of the folded portion made toproject inwardly in such manner as to provide a sufficient offset (madeof a single fold) to support the bottom, and there by save one or moreextra folds for producing the required shoulder or rest for the bottom,as has heretofore been frequently found In the practical manufacture ofmy im,

proved metallic vessel the blank sheets that form the body l are cut tothe required sizes, and one edge, which l shall term the lower, isturned in to form a single fold 2, and the extreme end of said fold 2 isturned down to form an inner member 2a, and the said fold member isagain turned up, as at 3, to form a reinforce or thickened part, whichends midway of the folds 2 2a, the purpose of which will be presentlyexplained. lt will be no-v ticed by reference to Fig. 3 that when thefolds forming the chime end of the vessel are first turned they do notlie in a compact or solidified manner against the outer wall of the rimX ofthe body, they leaving, as it were, the rest part Y of the foldloose and springy. Furthermore, when thus bent the rest portion does notuniformly project inward from the rim X, and the base part of the chimeis thus formed of one or more thicknesses, separated from each other,which makes an imperfect construction.

struction the folds 2, 2, and 3 are tightly pressed and the upper orrest portion Y made to project inwardly sufficient to form a rigid In mypresent con IOO and uniform resting flange or rim for the bQtf tom foldto seat upon.

In the manufacture of my said present construction of vessel the specialformingalld finishing of the chime end is eected at the same time thatthe sheet or body-'portion is passed press the sheet or body portion inshape for riveting, and for such purpose the chime end' is made to passbetween a pair of rolls a b, one of which has a iat bearing-surface a',adapted to bear-against the outside of the rim X, while the other, b,has an annular conveXed rim or iiange b', that engages the inside fold 2of the chime at a point just above the upper edge of the upturned fold3. This latter method of compressing the chime end of the vessel effectsa twofold advantage and result. Furthermore, it serves to crowd thefolds 2 2 tightly against the fold 3 and the folds 2, 2, and v3 tightlyagainst the lower end of the rim X, the whole being compressed soclosely together, as it were, to Vform practically a solidified orbottom rim having sufiicient thickness to withstand any rough use,jarring, dto., and, secondly, it allows for buc-k kling the inner fold 2at a point just over the upper end of the fold 3, and by reason of theflange b pressing against the fold surface X and the flat foldedportions 2 2 it will cause the upper end of the folded portions 2 2 toclose together as one member and to bulge inward suliiciently to form apositive rest-rim for the bottom to seat upon. After the chime isfinished inthe manner described the bottom plate 4 is inserted, saidbottom plate having the internal shape of the vessel, with itsperipheral edge made to snugly fit the inner wall of the vessel. Afterthe bottom is thus fitted in place the vessel is revolved through aswaging-machine,whicli forms an inwardlybent annular rim 5, that lapsover the upper end Of the rim, and thereby securely holds the saidbottom between two shoulders, the whole making a good andcheaply-constructed measure adapted for all the rough usages thatmeasures of this kind are ordinarily subjected to. through the bendingor forming rolls that Having thus described my invention, what I claim,and desire to secure by Letters Patent, is-

l. A metallic vessel the side walls of which are made of a single sheetof metal having one of its ends folded over inwardly as at 2, Asaid endbeing yfolded down adjacent the rim part ofthe chime end as at 2, itsfree end being turned up between the folds 2 2L to form a reinforce 3,the folded parts 2 2a being compressed together at a point above theupper edge of the reinforcefold 3 and the bottom member 4, substantiallyas shown and de,- scribed.

2. As a new article of manufacture, a metallic vessel the side Walls ofwhich are made of a single sheet of metal having its lower end turneddownwardly and outwardly to form a fold 2f, and then upward between thefolds 2 2, to a point nearly midway thereof, the contiguous portions ofthe folds 2 3 2 being closely compressed and formed with an annulargroove or depression at a point over the end of the reinforce portion 3,the upper end of the folds 2 2a, being curved inwardly to for-m anannular rest member Y, the bottom 4, the body of the vessel having anannular inwardly-projecting swaged flange for holding the bottom 4t uponthe annular seat portion Y, all being arranged substantially as shownand for the purposes described.
